Enter the change in shock position (in) and the change in wheel position (in) into the Motion Ratio Calculator. The calculator will evaluate and display the Motion Ratio.

## Motion Ratio Formula

The following formula is used to calculate the Motion Ratio.

MR = dS / dW

• Where MR is the Motion Ratio ( )
• dS is the change in shock position (in)
• dW is the change in wheel position (in)

## How to Calculate Motion Ratio?

The following example problems outline how to calculate Motion Ratio.

Example Problem #1:

1. First, determine the change in shock position (in).
• The change in shock position (in) is given as: 2.5.
2. Next, determine the change in wheel position (in).
• The change in wheel position (in) is provided as: 4.
3. Finally, calculate the Motion Ratio using the equation above:

MR = dS / dW

The values given above are inserted into the equation below and the solution is calculated:

MR = 2.5 / 4 = .625

Example Problem #2:

For this problem, the variables required are provided below:

change in shock position (in) = 4.5

change in wheel position (in) = 7

Test your knowledge using the equation and check your answer with the calculator above.

MR = dS / dW = ?
